Hi Dave, Daniel. Habanalabs pull request for 6.8. It's rather small this time, as Gaudi2 is very stable at this point. Same as in the previous cycle, it's a bit all over the place. A few uapi changes, mostly improvements and bug fixes. Full details are in the signed tag. Thanks, Oded The following changes since commit a0a28956b46ec7f16ce5d762ac5a124bb532da0d: Merge tag 'amd-drm-next-6.8-2023-12-08' of https://gitlab.freedesktop.org/agd5f/linux into drm-next (2023-12-13 15:55:55 +1000) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux.git tags/drm-habanalabs-next-2023-12-19 for you to fetch changes up to a9f07790a4b2250f0140e9a61c7f842fd9b618c7: accel/habanalabs: fix information leak in sec_attest_info() (2023-12-19 11:09:44 +0200) ---------------------------------------------------------------- This tag contains habanalabs driver changes for v6.8. The notable changes are: - uAPI changes: - Add sysfs entry to allow users to identify a device minor id with its debugfs path - Add sysfs entry to expose the device's module id as given to us from the f/w - Add signed device information retrieval through the INFO ioctl - New features and improvements: - Update documentation of debugfs paths - Add support for Gaudi2C device (new PCI revision number) - Add pcie reset prepare/done hooks - Firmware related fixes and changes: - Print three instances version numbers of Infineon second stage - Assume hard-reset is done by f/w upon PCIe AXI drain - Bug fixes and code cleanups: - Fix information leak in sec_attest_info() - Avoid overriding existing undefined opcode data in Gaudi2 - Multiple Queue Manager (QMAN) fixes for Gaudi2 - Set hard reset flag if graceful reset is skipped - Remove 'get temperature' debug print - Fix the new Event Queue heartbeat mechanism ---------------------------------------------------------------- Ariel Suller (1): accel/habanalabs: report 3 instances of Infineon second stage Dafna Hirschfeld (1): accel/habanalabs/gaudi2: fix undef opcode reporting Dani Liberman (2): accel/habanalabs: print error code when mapping fails accel/habanalabs: expose module id through sysfs Farah Kassabri (3): accel/habanalabs: update device boot error check accel/habanalabs: add log when eq event is not received accel/habanalabs: fix EQ heartbeat mechanism Moti Haimovski (1): accel/habanalabs/gaudi2: add signed dev info uAPI Oded Gabbay (1): accel/habanalabs: add support for Gaudi2C device Ofir Bitton (1): accel/habanalabs: remove 'get temperature' debug print Tomer Tayar (8): accel/habanalabs/gaudi2: assume hard-reset by FW upon PCIe AXI drain accel/habanalabs: set hard reset flag if graceful reset is skipped accel/habanalabs/gaudi2: get the correct QM CQ info upon an error accel/habanalabs/gaudi2: use correct registers to dump QM CQ info accel/habanalabs/gaudi2: add zero padding when printing QM CP instruction accel/habanalabs: update debugfs-driver-habanalabs with the device-name directory accel/habanalabs: add parent_device sysfs attribute accel/habanalabs/gaudi2: avoid overriding existing undefined opcode data Xingyuan Mo (1): accel/habanalabs: fix information leak in sec_attest_info() farah kassabri (1): accel/habanalabs: add pcie reset prepare/done hooks .../ABI/testing/debugfs-driver-habanalabs | 72 ++++++------ Documentation/ABI/testing/sysfs-driver-habanalabs | 12 ++ drivers/accel/habanalabs/common/device.c | 25 +++-- drivers/accel/habanalabs/common/firmware_if.c | 123 +++++++-------------- drivers/accel/habanalabs/common/habanalabs.h | 15 +++ drivers/accel/habanalabs/common/habanalabs_drv.c | 37 +++++++ drivers/accel/habanalabs/common/habanalabs_ioctl.c | 55 ++++++++- drivers/accel/habanalabs/common/hwmon.c | 4 - drivers/accel/habanalabs/common/memory.c | 7 +- drivers/accel/habanalabs/common/mmu/mmu.c | 1 + drivers/accel/habanalabs/common/sysfs.c | 42 ++++++- drivers/accel/habanalabs/gaudi2/gaudi2.c | 74 ++++++------- .../include/gaudi2/asic_reg/gaudi2_regs.h | 13 ++- .../habanalabs/include/hw_ip/pci/pci_general.h | 1 + include/linux/habanalabs/cpucp_if.h | 8 +- include/uapi/drm/habanalabs_accel.h | 28 +++++ 16 files changed, 333 insertions(+), 184 deletions(-)
